Difference between Regulated and Unregulated Power Supplies in Laptop Desktop Power Adapter
In a general sense, a power supply is any device that supplies energy to an electrical circuit. Taken this away, batteries are power suppliers for flashlights and power plants are power supplies for the electrical grid. Similarly, laptop desktop power adapter supplies power to the computers. But that’s not usually what we have in mind when we talk about laptop desktop power supplies. Usually, we use power supply to indicate a circuit or a device that adapts available power to the specific needs of one device or set of similar devices. In most of the settings, the available power, or input power, is AC, and the output power is DC. The laptop desktop power adapter is converting AC supply into DC power supply because these electronic devices are running on DC power supply units in general.
